Project Overview: Fluorescent to LED Lighting Upgrade
We were onsite at the Northwest ADHD Center to replace aging fluorescent fixtures with modern LED bulbs. The goal was simple:
• Improve energy efficiency
• Enhance lighting quality
• Address malfunctioning fixtures
LED lighting provides better light output, lower energy costs, and longer lifespan, making it an ideal upgrade for commercial spaces.
Initial Findings: Malfunctioning & Flickering Lights
During the walkthrough, we immediately noticed:
• Several fixtures completely out
• One fixture flickering continuously
• Aging fluorescent components
One light appeared to be a simple bulb failure, while another showed signs of a deeper electrical issue.
Troubleshooting the Flickering Fixture
After replacing the bulb, the flickering continued — confirming the issue was not the bulb itself.
Our inspection included:
• Checking internal wiring
• Inspecting the ballast
• Verifying power supply
All tested correctly. The issue was isolated to a faulty LED driver integrated into the socket, preventing a steady electrical connection.
Solution
- Identified the defective driver
• Documented findings
• Discussed options with the client
• Removed the bulb per client request to prevent further flickering
This approach avoided unnecessary replacements and ensured transparency.
Fixture Adjustments for LED Compatibility
Unlike older fluorescent bulbs with 360° light output, LED retrofit bulbs contain rear-mounted drivers.
To ensure proper light distribution:
• Fixture orientation was adjusted
• Bulbs were repositioned to face forward
• Covers were cleaned before reinstallation
These small adjustments significantly improved the final appearance.
Electrical Controls & Timer Switches
The exterior lighting system was controlled by:
• A timer switch
• Contactors within the electrical room
• Dedicated breaker (Circuit #6)
Because the work focused on fixture replacement, full power shutdown was not required, allowing efficient progress while maintaining safety.
Exterior Lighting Walkthrough & Observations
After reinstallation, we performed a full exterior walk-through and identified:
• One additional fixture without power
• One flickering fixture confirmed to be driver-related
• Uneven light distribution across the parking lot
These findings were documented and reviewed with the client.
Future Recommendations: Pole Lighting for Safety
Beyond the immediate scope, we evaluated the property for improved lighting coverage.
Our Recommendations
- Add new pole lights in the center parking area
• Improve lighting near the playground
• Balance light distribution across the property
Installation Considerations
- Power would need to be run from the main panel
• Trenching would likely be required
• Underground conduit installation would be necessary
While this represents a larger investment, it would significantly improve safety, visibility, and usability of the outdoor space.
Why Commercial LED Upgrades Matter
Upgrading commercial lighting:
• Reduces energy costs
• Improves reliability
• Eliminates frequent maintenance
• Enhances safety and appearance
Just as importantly, professional troubleshooting prevents unnecessary replacements and ensures long-term performance.
